Perhaps you should try some spelling variations:
controller python » controller with (Expand search), controller on (Expand search), controller to (Expand search)
disease processes » disease process (Expand search), disease progress (Expand search), these processes (Expand search)
decrease disease » decreases disease (Expand search), increase disease (Expand search), increased disease (Expand search)
using controller » using controlled (Expand search), tuning controller (Expand search), during controlled (Expand search)
python using » python coding (Expand search), python usando (Expand search), action using (Expand search)
decrease by » decreased by (Expand search), decrease in (Expand search), decrease of (Expand search)
by decrease » by decreased (Expand search), may decrease (Expand search), any decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease by decrease disease processes ) OR ( python using controller python programming ))~.
